AFAIK, no information_schema view shows anything at all about matviews.
This is intentional because matviews aren't SQL-standard objects.
It's therefore unclear how they should be represented in
information_schema (eg, do they belong in the tables view or the views
view, and if the former, what is their table_type?). Our project policy
is that rather than inventing extensions to the information_schema
standard, we just don't show nonstandard objects in information_schema.
